.To @ZZ whom it may concern:

Be it known that I, GEORGE H. HATHORN, of Ohester, in the county of Penobscot and State of Maine, have invented certain new and useful Improvements in Driving-Oalks; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw- 'ing, forming a part of this specification, in

section.

which the figure shows a perspective of my invention. l

My invention consists of an improved driving-calli, designed to be readily inserted and firmly held inthe boot or shoe, and at the same time be eapableof easy removal when desired. It will be readily understood 5 by reference to the accompanying drawing, in` which a perspeetive view of it is shown.

At a is shown the point,`angular in erossb shows a shoulder resting on the boot, and serving not only to keep the ealk from being driven too far in but also to keep the strain from the ealk itself. At c is a` rounded shoulder, while the remainder of the ealk, d, is square and provided With the bulging sides e, which insure its retention in the boot or. shoe.

To insert the ealk, a hole is made in the sole or heel and the ealk driven into place, Where it is rmly held. To remove it, a slight twisting motion is rst used, the sharp edges reaming out the hole in the leather and allowing the oalk to be drawn like an ordinary nail.

Instead of making the point et square,the shoulder b may be made square, if preferred.

What I claim as my invention is- The improved driving-calli herein described, provided with the point a, angular in Grossseetion, the shoulder b, for resting on the `boot-bottom, the round shoulder c, entering the leather of said bottom, and the bulging portion e, having an angular Gross-section, substantially as herein set forth and shown.

In testimony that I claim the foregoing I have hereunto set my hand this 24th day of December, 1883.
